Is it possible to create a new casting area for central southern England. It would make it a lot easier for posters and those answering, if instead of SE or SW there were a SW, SC and SE.
It's not as easy as that.
For a start, you haven't suggested which counties would be in this 'Central Southern England'.
I live 900m over the Hampshire border in Surrey. I'm 3.5 miles from the Berkshire border. The M25 is only about 12 miles up the road...
So, am I in the south or the south-east?
